Conversion Factors for Secondary
Units
The
420 Plus

convert a weight into many different types of units and
instantly display those results with a press of the
UNITS
key.
Secondary units can be specified on the FORMAT
menu using the SECNDR parameter, or by using EDP
commands.

Note
Multipliers in italics are preconfigured
Note
Multipliers are preconfigured within the
indicator. Manual entry is only necessary when
NONE is selected under UNITS. Long tons and
grain units listed in Table 7-6 cannot be directly specified
as primary or secondary units. For these or other unlisted
units of weight, specify NONE under UNITS.
Ensure that the secondary decimal point position is set
appropriately for the scale capacity in the secondary units.
If the converted value requires more digits than are
available, the indicator will display an overflow message
(OVERFL).
For example, if the primary units are short tons, secondary
units are pounds, and the secondary decimal point is set
to 8888.88, the indicator will overflow if 5 tons or more are
applied to the scale. With 5 tons applied, and a conversion
factor of 2000, the secondary units display needs five
digits to the left of the decimal point to display the 10000 lb
secondary units value.
